preferably adjustably both vertically and horicontaily, on depending arms 5 of horizontai arms 6, adjustably mounted. by means of longitudinal and transverse slots 7, on a slidahle reciprocating frame 8, adapted to slide on rollers 9, mounted in blocks fixed to pillars rising from the main frame. v .To the frame 8 are pivoted the ends of actuating-oars 11, one of which is slotted near its lower end and engaged in the slot nunihered 12 by a screw from the other bar. This connection between the actuating-bars permits of an adjustment one upon the other for the purpose f permitting the oxtension of the reci rocating frame, so as to therebyaccommo ate different sizes of cans. To the end of one of said bars 11 is pivotaiiy corineoted a long link 13, extending forward under the body of the frame and havin its front end pivoted to a slide-piece 14, ad1ustable on the arm15' of a bell-crank lever formed by said arm, 9. rec 'ng shaft 16, journaied in the frame, and an arm 17 extending upwardly from said shaft. The arm 17 is provided at its upper'end with a roller 18,bearing noon a cam 19, fixed to a shaft 20, journal'ed in the front part'of the frame of the machine-1'.

' is connected to said arm 17 and to Part of the frame and To all whom it may concern: I

Be it known that I, J omos Bnnnzmonn, a subject of the German Emperor, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Can-Flanging Machines, of which the; following is a l specification. 1'

My invention relates to can-flanging ma chines; and its object is to provide a machine by which cans may be rapidly and automatically fed to a flanging mechanism, flan ed at both ends, and'automatically discharge from the machine, whereby a rapid and continuous ilangii operation is obtained.

To t ris end my invention consists of the features and combination hereinafter described, and pointed out in the claims.

My invention is illustrated in its referred embodiment in the accompanying rawings; but it is obvious that the invention may e from those herein shown.

In the drawings, re 1 is a top plan view. Fig. 2 is a side e ovation. Fig. 3 is a plan view of a can-shifting frame. Fig. 4 is a section on line y 'y of Fig. 3; Fig. 5, a 1011 'tudinal side view, artiv in section, of one o the flangin roller-s afts, showing the roller pro :1 fixed serves to hold jected t ough thecan-guide disk and in opsaid ro ier against the cam and to assist the erative position; Fig. 6, a detail view of antireturn movement of the arm 17 to inward pofriction-ring; i 7, a section throng}; Fig. 6; sitlon and the corresponding forwardfeedmg Fig. 8, a vertica section throu h t swingmovement of the reciprocating frame 8'.

ing frame of the flangin -rol er and mam The shaft 20 carries all the actuating-cams mechanism. This shaft carries at its ends gears 22, which mesh with and are driven by pinions 23 on a main drivingshaft 24, journaled transverse y ofthe ma- .chine and provided at one end with a drivingpulle 24, which may be connected to any suita le source of power, and provided also .With an idle pulley 25. i

The can-supporting fingers 4 of the reciprocatingjfneed-frame extend forward between can gui g disks or plates 26, which are spaced apart a distance substantially the length of the can-body to be fiangigd and so as to inclose and guide the on of said body as itis flange jIn'the upper art of each disk or plate are circular he so 27, through w ch are adapted to be projected fla ro ls 28; Each roll 28 has a flangeforming collar 29 30. Theserolls and a hub are mounted on the ends of rotatable and shaft on line a: m of Fig. 1; ig. 9, a detail side for the different view of interior of can-guide plate; Fig. 10.3. detail front eleva ion of fianging-rolls in op erative osition; Fig. 11, a section l detail of can an rolls; Fig. 12, a detail of a flanged can.

' Referring tofthe drawings; 1 is a can-receptacle in winch the cans are placed for conveyance to the machine. 11 the embodiment of my invention herein set forth I have mechanparticularly adapted for formingflanges on cylindrical can-bodies. receptacle is provided withia downward-inclined chute ortion 2, having an open bottom and stopliigs 3, which prevent the can from escaping descends thesame. Located beneath the eceptacle and at the end of the chute portion is a pair of curved can-holding fingers 4, which receive a can from the chute. .Thcse fingers are mounted,

wise result from lpermit the y- 7 outer provided with rollers .44, which bear ag vided with a slidable shafts 31., These sha ts are journaled and guided in disks 26 and'their bearings 32 and m uprightbearings 33. Near their outer ends each shaft is pro pinion34, engaging a gear 35 on the main driving-shaft 24, wh shafts 31 are continuously rotated;

Each shaft is provided with two or more collars 36, fixed on the shaft against rotation and against sliding movement thereon. Between these collars extend studs 37 from the forked end of a rockin lever 38, pivoted on a stud 39. On each side of the studs 37 and between .the sameand the collars 36 are antifriction'bearin ri=ngs, all movable freely on the shaftand tlie outer r'in s 40 being merely plaign-surt aeeiwhile the m1ddlering4l is prowiijth; ahtifri'ction bearingballs '42, in wulltersunk recesses in thefring so as to project through on each side against the ion itudinally ring40. The objectof this arrangementis 40 and the collars 36 to permit the end rings balls on the middle to turn freely against the ring when either of the inside rings is pressed must by a stud 37 of the roe lever'38, life pressure of such lever being such as to roller to bind, so that it will this bind come by the ball-bearings, which ring'and collar to rotate free he inner one of the collars Between t l and fixed on the sh. t 31 ongitudinal movement ereon, but capab provided with adjusting con proifctiugfrom the ends'of the eir heads bear one side-and against roll 8 at the B these means the extent of projection of theIroll 28 into the hangingipace between the. can-guide disk may be conveniently'gadjusted.
